GAS SUPPLY FOR AUXILIARY APPLIANCES Filed Nov. 5, 1948 INVENTOR We LTERKENNEDY ATTORNEY Patented Jan. 6, 1953 UNITED STATES PATENT '0 F Fl CEGAS sorrnr non AUXILIARY APPLIANCES Walter Kennedy, Clifiside Park, .1.Application November 5, 1-948, Seria1'No.'58,56-9 9 Claims. (o1. 126.3 9

This invention relates to gas stoves, range and the like. Moreparticularly, the invention deals with a gas supply means for apparatusof this class to service an auxiliary appliance, such for example, as abroiler, oven or the like. Still more particularly, the. inventiondeals. with a gas supply means comprising movable parts coupled with apart of the range, so that the supply is normally concealed when not inuse, and can be extended over the top of the stove or range 'tobeaccessible for use.

The novel features of the invention will be best understood from thefollowing description when taken together with the accompanying drawing,in which certain embodiments of the invention are disclosed, and inwhich the sepa- 2 disposed outwardly of the wall ill for regulating thesupply of gas to "the horizontal pipe 111..

rate parts are designated by suitable reference the -line 2-2 of Fig. l,and indicating the gas supply means in collapsed and concealedpositions, in dot and dash lines.

In gas stoves or ranges; as conventionally con- 7 structed, no means hasbeen provided to service an appliance used in conjunction therewith. 7It a has been old to apply an auxiliary oven on top of a stove and heatthe same. byone of the conventional top burners of the range. "It hasalso been A known to service a portable gas burner through;

the medium of a flexible tube or hose.

'Ihefpurpose of :my' invention is to provide a neans".for supplying gasso as to service an auxiliary appliance which canbe arranged upon thetop of the stove or gas range, the means being normally concealed withinthe wall structure of the range and adapted to be extended in positionto facilitate coupling with the auxiliary appliance, such as a broiler,oven or the like. I

In Fig. 1 of the drawing, I have diagrammatically outlined the upperportion of a gas stove or range .III, M representing par-tot the frontwall, 12 the top wall and at 13 is shown a raised v and hodded back wallportion which projects Such raised walls as,

above the top wall It the wall l3 are commonly employed in modern stovesor ranges, At I4 I have shown the nor mal gas supply pipe which suppliesgas to the upper burners of v the range, and with this pipe is coupled avalve l controlled by a knob-1'6 Coupled with the rear end portion of!the pipe H, is an elbow-shaped fitting 18 having a projection t8 seatingupon a bracket support 28 suitably fixed to a rear wall portion 2| ofthe range.

The fitting i8 terminates at its upwardly ex tended end in a conical ortapered portion 22, below which is an outwardly extending collar 23forming :a seat for a coil spring 2-4. .At is shown a tubular arm havinga lowerconi'cal bore 215 fitting snugly on the conical portionfi; saidend having an externally threaded portion 21 for reception of a sleevenut 28 which acts upon the spring '24 to tensio-nally support the arm 25in engagement with the fitting I18 while facilitating "rotation of the:arm. around the fitting.

Extending from the end portion 26' is a horizontal part 29 on the arm,which terminates at its end in a right angle extension 139 having aclosed end wall, as clearly seen at 3|, in Fig. l of the drawing. Theextension 30 is apertured, as. :seen at 32, to receive a nozzle 3:3through which gas is discharged into a supply tube .34 of an auxiliaryappliance, indicated in dot and dash lineszat in Fig. .1.

A mit- 343 is mounted on the nozzle to secure the-same to the end 30 ofthe arm, and also to secure a bracket .3] to the arm, as well. as. a cup5.8. The cup 38 has a. circumferentieilly spaced air passages 39 whichare controlled and regulated by a conventional apertured and ad=a'ustabrle sleeve =40 in controlling air supply to govern the gaseousmixture passed through the tube 34 to the auxiliary appliance 3-5,.

The lower end of the tube Q34 .is reduced in diameter, as seen at M, toiacili-tate insertion into the cup 38, the reduced portion joining thetube in a bevelled wall 42, which wall has .cir cumferentially 'spacedapertures 43, through which air is free to pass into the tube 34,preferably ata point adjacent the nozzle '33. It will appear from :aconsideration of "Fig. 1, that the end of the tube 34 adjacent the bevel42 fits snugly in the upper end portion of the cup 88. "The irontwall ofthe hood 13 has a large aperture 44 through which the arm 25,.togetherwith the cup and the other parts attached to the arm, is free to swingfrom the dot-dash concealed position indicated in Fig. 2, to theprojected position shown in full lines in Figs. '1 and 2.

Thebracket 31 is secured to the inner surface of a cover 45 considerablylarger than the opening 44, and adapted to conceal this opening as wellas everything rearwardly thereof, when the cover is in closed position,indicated in dot-dash lines in Fig. 2. The cover 45 also preferably hasbelow the bracket 31, an indenture 46, note Fig. l, which forms afinger-grip facilitating outward swinging of the cover together with thearm 25.

In the normal use of the gas stove or range, the cover 45 will be inclosed position and the arm 25 disposed within the rear hodded part iiiof the range, thus the range can be fully and completely used for itsnormal purposes, without blocking any part of the surface thereof.Whenever it is desired to use an auxiliary appliance, such for example,as a broiler, of the type and kind disclosed in my prior applicationSer. No, 787,239 of November 20, 1947, now Patent No. 2,572,870, allthat is necessary, is to pull outwardly on the cover 45, which willswing the arm 25 into the full line position shown in Figs. 1 and 2,exposing the cup 38 for the reception of the tube 34 of the appliance35. In other words, the appliance is simply placed downwardly on the topwall [2 of the range, the tube 34 being guided into the cup in thisoperation and the appliance can be Supported between front feet, one ofwhich is indicated in dot and dash lines at 47 in Fig. 1 of the drawingand the rear end will be supported by the lower end portion M of thetube 34.

Assuming that the air shutter it has been adjusted for proper airsupply, the knob l5 can then be moved into position to supply gas to thenozzle 33 to ignite the broiler for use. When the broiler has served itspurpose, it can be lifted from the top of the range and the door orcover 35 moved into its closed position, as indicated in dot and dashlines in Fig. 2 of the drawing. The lower end of the tube 34 hasadjacent and slightly above the nozzle 33, the usual venturi 34.
